Definitions

  • the invention relates to the field of lighted switches or pushbuttons and in particular to switches or pushbuttons which are adapted for use in daylight and half-light or night conditions.
  • each pushbutton is associated with a light source which illuminates the button when the headlights are turned on. This allows the drivers to easily locate the pushbutton at night or in half-light conditions but gives no indication of whether the controlled device is on or off. In order to give such indication of the state of the controlled device, it was suggested to provide the pushbutton with a second light source which is off when the controlled device is in an off state and which illuminates the pushbutton when the controlled device is in an on state.
  • the major drawback of such implementation of two light sources is that at day time the light of the second light source is not powerful enough for the driver to know at a glance the status of the controlled device, and at night the added lights of the two light sources are too powerful and therefore dazzle or at least distract the driver.
  • one object of the invention is a method, for selectively illuminating a pushbutton or switch controlling a device having at least two states (off and on), which gives, in any illumination conditions, the status of the controlled device without dazzling the driver, and in half-light or night conditions allows an easy localization of the pushbutton.
  • the method comprises the steps of:
  • the invention By activating, in daylight, the two light sources when the controlled device functions, the invention allows the drivers to catch at a glance the status of the device even in bright light conditions. Whereas by activating, in half-light or night condition, only the second light source when the device is on, the invention gives an easy to catch information without any risk of dazzling or distracting the driver. This is especially important when the pushbuttons or switches are grouped in a same area.
  • the first light source enables the drivers to easily locate the pushbutton in the half-light or night conditions.
  • a further object of the invention is an apparatus for controlling a device having at least two states (off and on), this apparatus implementing the method of the invention.

  • the two light sources are of different colors.
  • the two light sources may be of two different primary colors either additive or subtractive.
  • One of the light sources may also be of a secondary color, the other light source being of a primary color which is a component of said secondary color.
  • the first light source can be of a primary color and the second light source of a secondary color comprising a component of the primary color of the first light source. Therefore, the same color code will be used when the controlled device is on, either at night or in daylight, as the color given by the two illuminated light sources together will be close to the color given by the second light source alone.
  • the first light source is yellow and the second light source is red, these warm colors reducing the risk of dazzling the driver.
  • the light sources of the invention may be of various types.

  • the same ECU 22 could also perform the functions stated above of being a control interface between the pushbuttons and the associated devices.
  • the ECU 22 can also be connected to a vehicle communication data bus, such as a CAN-bus, on which many operating parameters of the vehicle are available.
  • the automotive vehicle according to the invention further comprises means 25 for determining the luminosity conditions, preferably more particularly around the pushbuttons 2 to 5 environment, i.e. in the present embodiment, the driver's cab of the automotive vehicle.

This monitoring can be performed continuously, or from time to time, and/or on the occurrence of a particular event of which the ECU 22 can be informed.
  • the determination of whether the ambient luminosity corresponds to daylight or not can comprise an algorithm based on a comparison of the measured luminosity with a threshold.

  • the ECU can also use information from several sensors to make such determination, for example by using the information from a rain detection sensor, from a vehicle speed sensor, etc... For example, the rain information could be used to set a different threshold.
  • ECU 22 turns off all the light sources 20, 21.
  • the ECU 22 turns on the two corresponding light sources 20, 21 as illustrated on figure 3.
  • the addition of the light of two light sources 20, 21 gives a powerful red-orange light which allows the driver to know at a glance that the corresponding device works and this even in bright light conditions.
  • the ECU 22 turns on the first light sources 20 of all the push buttons in order to help the driver to easily find the corresponding pushbutton when he wants to activate a particular device or system.
  • the driver turns on a particular device, for example the seat heating system 6, by pressing the corresponding pushbutton 2, the ECU 22 turns off the corresponding first light 20 and turns on the corresponding second light source 21. Therefore, according to this example and as shown on figure 5, in half-light or night conditions, the pushbutton 2 corresponding to the activated device of system 6, is only illuminated by the corresponding red second light source 21 whereas the other pushbuttons 3 to 5, which corresponding devices are turned off, are only illuminated by their corresponding yellow first light source 20.

  • the ECU 22 controls the light sources 20, 21 according to the status of the controlled devices or systems 6 to 9 but it should be understood that the ECU 22 may also control the light sources 20, 21 according to the positions or status of the pushbuttons 2 to 5. It should be also understood that the pushbutton 2 may also be replaced by switches having two positions, a position on and a position off.
  • the determination means comprise the photoelectric cell which senses directly the luminosity conditions around the pushbutton environment but, on vehicles not equipped with light sensors, determination means could also detect whether the headlights are on or off, the headlights on being considered by the determining means as half-light or night conditions and the headlights off being considered by the determining means as daylight conditions.
  • the determining means would therefore monitor whether the driver has turned the head lights on or off.
  • the determination means may then merely comprise an electrical wire connected to the headlight power supply and to the ECU 22, thereby informing the ECU that the headlights are on or off.
  • the same type of determination means could also or alternatively monitor whether the interior lighting of the cabin of the vehicle is on or off, due to the driver's express intention, or due to an automatic process which can be linked to the opening of a door.
  • the means to evaluate the luminosity for the headlight system could be also used as part of the determining means used in the apparatus according to the invention.
  • the algorithms to determine between daylight or nightly could be the same or not and have the same thresholds or not for headlight control and for pushbutton illumination control.
